Specification of Letters Patent.

Application filed April 15, 1t .6. Serial No. 91,313.

To aZi whom it may concern:

Be it known that I, Elana S. O

a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in StylusvAdapters; and I do hereby declare the following full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of referencemarked thereon,'which form a part of this specification.

This invention relates, generally, to improvements in phonograph apparatus; and the present invention has reference, more particularly, to a stylus-adapter or holder,

and a needle or stylus therefor, both of a novel construction, with a view, primarily, of providing a device for permitting the be used'a great many times upon the same disk-record, without destroying the record-producing face of the disk or plate.

My present invention has for its principal object to provide a novel and.simply-constructed stylus-adapter or holder and nerdle therefor of the general character hereinafter set forth and for the purpose above stated.

The invention has for its further objectto provide a novel stylus-adapter with which the needle or stylus is capable of easy adjustment, so that the same needle or stylus may be used for varying the tone produced by the sound box of the phonograph.

A further object of the present invention is to produce a novel and simple stylus adapter, in which the stylus or needle is held in such a manner and is of such construction, the. the accompanying rattle and scratching sound, when playing a record are reduced to a minimum, so as not to be perceptible- Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

stylus or needle being The stylus-adapter and stylus or needle of the present invention are more especially adapted for use with that type of soundrecord impressions a series of lateral or horizontal indentations or impressions formed in the face of the sound-diskpr' record.

With the various objects of the present invention in view, the said invention consisfis primarily, inthe novel stylus-adapter, an

more fully set forth; and, the invention consists, furthermore, in the novel arrangemerits and combinations of the several devices and parts,'as well as in the details of the construction of the same, all of which will be moreiully described in the following specification and then finally-embodied in the clauses of. the claim which are appended to and which form an essential part tion of a socket-member or element shown and the novel stylus-adapter in said Fig. 1, and stylus or needle, the adapter being represented in vertical section and the shown in elevation; and Fig. 3 is an end View of the same, said Figs. 2 and .3 being made on an enlarged. scale.

or groo" es consisting of 1 needle being shown 2 and 4, said views showing other modifications', but all embodying the principles of the present invention; and Fig. 9 is an end view of the construction represented in said Fig. 8.

Figs. 10 and 11 are vertical sectional repres'entations of stylus-adapters and elevations of needles for the same, said views illustrating other modifications of the principles of the present invention.

Similar characters of reference are employed in the said above described views, to indicate corresponding parts.

Referrin now to the said drawings, the reference-c aracter 1 indicates the usual sound-box of a phonograph, or the like, With the lower portion 2 of which are suitably connected the usual fulcrum points or projections 3 upon which is fulcrumed the pivotframe 4 of an upwardly extending vibratorarm 5, the upper end-portion of which is connected with the diaphragm of the soundbox in the usual and well known manner.

Suitably connected with and extending downwardly from the said pivot-frame 4 is an arm or post-like element, as 6, which is formed in its lower end-portion with a receiving socket, as 7, and is also provided with a binding or tightening screw, as 8, the said socketed portion being for the purpose of receiving the stylus adapter, and the setscrew serving to secure the latter in its operative position and relation to the said arm or post-like element 63, substantially as illustrated in Figs. 1, 2, 1, 6, 7,,and 8 of the drawings.

The stylus-adapter consists, essentially, of a main body 10 adapted to be inserted in the receiving socket 7, of the above-mentioned arm or post-like element 6, being secured in the said receiving socket 7 by means of the said binding or tightening screw 8. That portion of the said main body 10 which extends beyond the end-surface 12 of the said arm or post-like element 6 is externally screw-threaded, as at 13, and is made with a pin or stylus -receiving socket 14:, in which is inserted a in or stylus 15, of any suitable material and of the general configuration shown in the accompanying drawing Screwed upon the screw-threaded portion 13 of the said main body 10 is a hollow cap or nipple, as 16, see Figs. 1, 2 and 3 of the drawings, said cap'or nipple being provided v in its closed end-portion 17 with a hole or perforation, as 18, from which the free endportion of the needle or stylus 15 projects for operative engagement with sound-disk or record. As shown in Fig. 2 of the drawings, there may be mounted upon a portion of the said main body 10, above the marginal edge 19 of the said adjustably disposed cap inseam rubber or any other analogous material 0 fabric or the like.

In lieu of the style of cap or nipple 16 hereinabove described, a cap or nipple 16 of the form shown in Figs. 4 and 5 may be used, in which case the lower end-portion of the cap or nipple is made with a cross-cut or slit, as 22, to provide two spring-like clamping members, aS 23 and 24, which may be made with oppositely disposed grooves or channels, as 25, all arranged for embracing the needle or stylus, as shown in Fig. 5, and for properly securing the said needle or stylus in its operative position, as will be clearly evident. In all other respects, the arrangement of the remaining parts of the complete stylus-adapter is the same as that described in the above and illustrated in said Figs. 1 and 2 of the drawings.

If desired, the stylus-adapter may eomprise a main body, as 26, shown in Fig. 6 of the drawings, in which case the screwthread 13 is disposed with, the said body bein formed with a smooth shank-like member, as 27, upon which the hollow cap or nipple 28, provided with a hole or perforation 29 in its closed end, is slipped and may be secured in its adjusted position by a set-screw 30. Within the hollow cap or nipple 28 is a flexible collar 31, as in the constructions illustrated in Figs. 2 and l of the drawings, the other flexible collar 20 hereinabove mentioned being desirably omitted in this construction of stylus-adapter.

In Fig. 7 of the drawings, I have shown a stylus-adapter comprising a main body 32 with which is integrally connected, at the one end thereof, a stylus or needle-like element, as 33, the remaining parts of the stylus-adapter being made in the manner of the construction represented in Fig. 2 of the drawings.

In this construction, I have also dispensed with the use of the flexible collar 20, al-

though such collar 20 may be employed or nipple, the same stylus or needle can be employed for changing or roducing tones or sounds of difierent intensities, and furthermore, the stylus or needle being always retained in the same fixedposition with relation to the main body of the stylusadapter, there will be no undue and irregular wearing awayof the contact end of the stylus or needle, or of the sound-producing surface of the record or disk, thus enabling the use of the same stylus or needle many times.

The use of the flexible collar or collars is also of great advantage, such collar or collars preventing undue vibration, and thereby overcoming the annoying scratching sound or rattle so often accompanying the reproduction of the sound-record.

In Fig. 8 of the drawings, 1 have represented another form of stylus-adapter made according to and embodying the principles of the present invention.

In this construction, the reference-character 34 indicates the main body of the needle-holder, the same being formed with 'a receiving socket 35, and a pair of downwardly extending clamping fingers, as 36 and 37 which are formed with oppositely placed grooves or channels, as 38, see Fig. 9 of the drawings, in which the needle or stylus 39 is placed, and suitably held or clamped between the said spring-like fingers 36 and 37. The stylus-adapter is inserted in. the socketed portion of the post-like element or arm 6, and secured in place by means of the binding or tightening screw 8, substantially as illustrated in said Figs. 8 and 9 of the drawings. Other modified constructions of the stylus-adapter are illustrated in Figs. 10 and 11 of the drawings.

In these forms of adapters the referencecharacter 40 indicates the main body of the same, being made in the form of a shank adapted to be inserted and secured in the socketed portion of the arm or post-like element 6 hereinabove mentioned. Connected with the said main body 40 is'an enlarged portion or member 41 which is hollow as shown, and is exteriorly screw-threaded, as Extending downwardly from the said member 41 are a number of clamping fingers, as 43, the said fingers tapering inwardly with relation to thesaid device, so as to embrace and engage the stylus or needle 44, in the manner illustrated in Fig. 10, or to embrace and engage a vibrationreducing ring or sleeve, as 45, which is mounted upon the stylus or needle, as shown in Fig. 11. In the form illustrated in said Fig. 10, a vibration-reducing sleeve 46 is mounted upon-the stylus or needle 44 directly beneath the needle-engaging ends of the fingers 43. Secured upon the screwthreaded part 42 of the enlarged portion or member 41 is a tightening cap or nipple, as 47, having a tapering portion 48 and a closed end 49 provided with-a hole or perforation, as 50, into and through which the record-engaging end-portion of 'the stylus said or needle projects and extends from the said end 49 of the tightening cap or nipple 47, as illustrated in the drawings.

The screwing up of the said cap or nipple 47, brings the tapering portion 48 in binding engagement with the clamping fingers 43, thereby causing the lower ends of the fingers to firmly clamp or grip the stylus or needle'so as to hold the same positively in its operative position, in the manner indicated in said Fig. 10 of the drawings; or, causing the lower ends of the said fingers to firmly clamp or grip the ring or sleeve 45, resulting also in securely retaining the stylus or needle in its operative position, as will be clearly understood from an inspection of Fig. 11 of the drawings.

The arrangement of the needle or stylus with the various adapters herein-above described is such that the engaging end of the needle or stylus uniformly wears away the bottom of the sound-groove or depression in the sound-disk or record, and not the sides of the said groove,

fulness of the stylus or needle, so that the latter can be used over and over a great many times.

I am fully aware that changes may be made in the general arrangements and combinations of the various devices and parts,

without deterioration of I the record, and without destroyingthe useas well as in the details of'the construction of the same, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the claims which are appended to the said specification. Hence, I do not limit my present invention to the exact arrangements and combinations of the several devices as described in the nor do I confine myself to the exact details of the construction of the said parts, as illustrated in the accompanying drawings. I claim 1. A stylus-adapter for phonograph soundboxes comprising a main body provided with an externally screw-threaded portion and a stylus extending from the end there- 01, combined with a hollow nipple-like elemounted upon said stylus.

. 2. A stylus-adapter for phonograph soundboxes comprising a main body and a stylus point extending from one end of said main ody and an adapter means carried by said said specification,
